Static line
Static line is a type of sky diving training
Static line training and instructor assisted static line training requires the longest amount of ground training, about 5 hours, before you get into the air.
You are then taken to a low altitude for your first jumps and a line attached to your ripcord actually pulls it for you, just so you get a feel for the jump.
After a couple of times with the static line, you will then need to show your instructor that you understand how and when to pull your own cord, but the line will still be attached and do it for you.
Eventually you will be allowed to pull your own ripcord and elevate to higher jumps.
